NPE in maven-site-plugin when referring to parent projects

[Markus Umefjord <ma...@ladok.umu.se>]

Hi,

 

I'm using a configuration with two base projects; BaseJava and BaseEJB
(extends BaseJava). I have configured the maven-site-plugin in the BaseJava
like this:

 

[BaseJava/pom.xml]:

.

<build>

.

<plugins>

            <plugin>

                        <groupId>org.apache.maven.plugins</groupId>

                        <artifactId>maven-site-plugin</artifactId>

                        <version>2.0-beta-7</version>

                        <configuration>

 
<outputDirectory>${outputDirectory}/site</outputDirectory>

 
<inputEncoding>ISO-8859-1</inputEncoding>

 
<outputEncoding>ISO-8859-1</outputEncoding>

                        </configuration>

            </plugin>

</plugins>

.

</build>

.

<reporting>

 

 

When calling site:site in projects that extend BaseJava there is no problem,
but when calling from projects that extend BaseEJB the site-plugin fails
with an NPE:
